How to Make Ink from Black Walnuts?
Making ink from black walnuts involves extracting the natural pigments from the hulls of the walnuts through a simple process of simmering and straining, resulting in a rich, brown, and archival-quality ink that can be used for writing, drawing, and dyeing.
A Journey Back to Nature: The Allure of Black Walnut Ink
The art of creating ink from natural sources is experiencing a resurgence, fueled by a desire for sustainable practices and a connection to traditional methods. Black walnut ink, in particular, offers a readily available and visually appealing alternative to commercially produced inks. Beyond its aesthetic appeal, crafting your own ink provides a unique sense of accomplishment and a deeper appreciation for the natural world. From its historical use in calligraphy to its contemporary applications in art and crafts, black walnut ink offers versatility and a timeless charm.
The Benefits of Making Your Own Black Walnut Ink
Why choose black walnut ink over commercially available options? The benefits are numerous and compelling:
- Sustainability: Utilizing fallen walnuts reduces waste and promotes environmentally friendly practices.
- Cost-effectiveness: Walnuts are often free and plentiful, making ink production very affordable.
- Archival Quality: Properly prepared black walnut ink is known for its lightfastness and longevity, ideal for preserving important documents or artwork.

- Connection to Nature: The process itself is a rewarding experience, fostering a deeper understanding of natural resources and traditional crafts.
Gathering and Preparing the Black Walnuts
The key to vibrant, lasting ink lies in using the right walnuts and preparing them properly.
- Harvesting: Collect black walnuts in the fall, ideally after they have fallen from the tree. Look for walnuts that are still intact and have not begun to decompose. Gloves are essential, as the husks will stain skin and clothing.
- Cleaning: Remove the outer green or brown husk, often referred to as the hull. This is best done outdoors, wearing gloves and old clothes. A sharp knife or a specialized hulling tool can be used.
- Drying: Once the hulls are removed, allow them to dry completely in a well-ventilated area. This process can take several weeks. Drying prevents mold growth and concentrates the tannins responsible for the ink’s color. Laying them on a screen or rack is ideal.
The Ink-Making Process: Step-by-Step
Here’s a detailed guide to creating black walnut ink:
- Gather Your Supplies: You’ll need dried black walnut hulls, a stainless steel or enamel pot (avoid aluminum), water, a heat source, a strainer, a cheesecloth, jars or bottles for storage, and a mordant (optional, such as vinegar or salt).
- Simmer the Hulls: Place the dried walnut hulls in the pot and cover them with water. The ratio should be approximately 1 part hulls to 2 parts water. Bring the mixture to a simmer over medium heat.
- Cook for Several Hours: Let the mixture simmer for 2-4 hours, or until the water turns a rich, dark brown color. Stir occasionally to prevent sticking. The longer you simmer, the darker the ink will be.
- Strain the Mixture: Allow the mixture to cool slightly, then strain it through a fine-mesh strainer lined with cheesecloth. This will remove any solid particles from the ink.
- Reduce (Optional): For a more concentrated ink, return the strained liquid to the pot and simmer it over low heat until it reaches the desired consistency. Be careful not to scorch the ink.
- Add a Mordant (Optional): Adding a mordant, such as a small amount of vinegar or salt (about 1 tablespoon per quart of ink), can help improve the ink’s lightfastness and prevent it from fading over time. Experiment to find the mordant and amount that works best for your walnuts.
- Store the Ink: Transfer the ink to clean, airtight jars or bottles. Store it in a cool, dark place to prolong its shelf life.
Common Mistakes and How to Avoid Them
Even with careful preparation, mistakes can happen. Here are some common pitfalls and tips for avoiding them:
- Using Rotten Walnuts: Rotten or moldy walnuts will produce weak or unusable ink. Always use fresh, clean, and properly dried hulls.
- Overboiling: Overboiling can scorch the ink, resulting in a burnt smell and a less desirable color. Simmering is key.
- Using Aluminum Pots: Aluminum can react with the tannins in the walnuts, affecting the ink’s color and quality. Use stainless steel or enamel pots instead.
- Insufficient Straining: Inadequate straining can leave sediment in the ink, clogging pens and brushes. Always strain the ink thoroughly through cheesecloth.
- Ignoring Mold Growth: Mold can form in the ink if it is not stored properly. Add a preservative, such as a few drops of clove oil, and store the ink in a cool, dark place.
- Forgetting Gloves: Black walnut hulls will stain your skin, clothes, and anything they come into contact with. Wearing gloves and protective clothing is essential.
Testing and Adjusting Your Ink
Before using your black walnut ink on a final project, it’s essential to test it. Write or draw on a piece of scrap paper and observe how the ink behaves. If the ink is too thin, simmer it for a longer period to concentrate it. If it’s too thick, add a small amount of distilled water. Pay attention to how the ink dries and whether it fades over time. Adjust the mordant or cooking time as needed to achieve the desired results.
Storing and Preserving Your Homemade Ink
Proper storage is crucial for preserving the quality of your black walnut ink.
- Airtight Containers: Use airtight jars or bottles to prevent oxidation and evaporation.
- Cool, Dark Place: Store the ink in a cool, dark place, away from direct sunlight and heat.
- Preservatives (Optional): Adding a preservative, such as a few drops of clove oil or witch hazel, can help prevent mold growth and extend the ink’s shelf life.
- Regular Inspection: Periodically check the ink for signs of mold or spoilage. If mold forms, discard the ink.
